Bacteriostatic water is USP-grade water containing 0.9% benzyl alcohol, used to reconstitute lyophilized research compounds. The benzyl alcohol inhibits bacterial growth across multiple withdrawals.
Also referred to as: Bacteriostatic water, BAC water, reconstitution solvent.
Bacteriostatic water contains 0.9% benzyl alcohol, an organic alcohol that acts as a bacteriostatic agent by disrupting microbial cell membranes and inhibiting bacterial growth. This preservative allows the same vial to be entered multiple times for sterile withdrawals while limiting microbial proliferation. The benzyl alcohol concentration defines its function in laboratory reconstitution chemistry.
Preservative-free sterile water is intended for single use, whereas bacteriostatic water contains 0.9% benzyl alcohol, letting a vial be accessed repeatedly. The key chemical difference is this added preservative: plain sterile water offers no antimicrobial protection after opening, while bacteriostatic water resists microbial growth across multiple withdrawals in research handling.
Bacteriostatic water is stored at controlled room temperature, kept sealed, and protected from contamination between withdrawals. The benzyl alcohol is compatible with many lyophilized research compounds, though some sensitive peptides are noted to prefer preservative-free solvents. Vials are typically labeled with an opening date and discarded after the preservative's effective window in laboratory use.
Yes. Every batch of Bacteriostatic Water is independently tested by HPLC and mass spectrometry, and ships with a lot-specific Certificate of Analysis verifying USP Grade purity and molecular identity.
Store lyophilized Bacteriostatic Water at -20°C for long-term storage or 2-8°C short-term. After reconstitution, keep refrigerated at 2-8°C and avoid repeated freeze-thaw cycles.
No. Bacteriostatic Water is sold strictly for in-vitro research and laboratory use only. It is not a drug or supplement and is not intended for human or animal consumption.
